They Walked Into Darkness is based on the Cherokee Indian 'Trail of Tears', a grueling 1,000 mile forced march to Indian Territory in Oklahoma in 1838. It tells of a teenage Cherokee girl named Ellie Sheldon Starr. Her people are rounded up by Government troops and forced to walk in the snow to a 'promised' new land.
